Answer:

∠ 2 = 104°

Step-by-step explanation:

- 8x - 48 = 9x + 275 [ alternate angles are equal ]

-8x - 9x = 275 + 48

-17x = 323

x = -19

9x + 275 = 9 × -19 + 275

= - 171 + 275

= 104°

∠ 2 = ( 9x + 275 ) [vertically opposite angles ]

∠ 2 = 104°

Given that D is the midpoint of AB and B is the midpoint of AC, which statement must be true?

abruzzese [7]

Answer:

AC =4DB

Step-by-step explanation:

D is midpoint of AB .So, AD = DB

AB = 2DB ---------- (i)

B is the midpoint of AC.So, AB = BC

AC = 2AB

= 2*2DB {FROM 1}

Can someone please help me please I really need help please help

mr Goodwill [35]

Answer:

K'(4, -4)
L'(8, -4)
M'(8, 8)
N'(4, 8)

Step-by-step explanation:

Dilation centered at the origin multiplies every coordinate value by the scale factor.

K(1, -1) ⇒ K' = 4(1, -1) = (4, -4)

L(2, -1) ⇒ L' = 4(2, -1) = (8, -4)

M(2, 2) ⇒ M' = 4(2, 2) = (8, 8)

N(1, 2) ⇒ N' = 4(1, 2) = (4, 8)

The gas tank of Tyrell's truck holds 19.8 gallons. when the tank empty, Tyrrell fills it with gas that costs $3.65 per gallon. a

Tems11 [23]

It is given in the question that

The gas tank of Tyrell's truck holds 19.8 gallons. when the tank empty, Tyrrell fills it with gas that costs $3.65 per gallon.

It means cost of one gallon of gas is $3.65 .

And the tank hold 19.8 gallon . So cost of 19.8 gallon is

$= $3.65*19.8 = $72.27$

Therefore about $72.27 it will cost to fill the tank .

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

777dan777 [17]

Given:

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

To find:

The equation of the perpendicular bisector of NY.

Solution:

Midpoint point of NY is

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

$Midpoint=\left(\dfrac{-11+3}{2},\dfrac{5-3}{2}\right)$

$Midpoint=\left(\dfrac{-8}{2},\dfrac{2}{2}\right)$

$Midpoint=\left(-4,1\right)$

Slope of lines NY is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{-3-5}{3-(-11)}$

$m=\dfrac{-8}{14}$

$m=\dfrac{-4}{7}$

Product of slopes of two perpendicular lines is -1. So,

$m_1\times \dfrac{-4}{7}=-1$

$m_1=\dfrac{7}{4}$

The perpendicular bisector of NY passes through (-4,1) with slope $\dfrac{7}{4}$ . So, the equation of perpendicular bisector of NY is

$y-y_1=m_1(x-x_1)$

$y-1=\dfrac{7}{4}(x-(-4))$

$y-1=\dfrac{7}{4}(x+4)$

$y-1=\dfrac{7}{4}x+7$

Add 1 on both sides.

$y=\dfrac{7}{4}x+8$

Therefore, the equation of perpendicular bisector of NY is $y=\dfrac{7}{4}x+8$ .
